Title: Manufacture of cadmium negative electrode plate
Inventor: SUZUKI JUN
IPC: H01M10/52
Filed: 1987-12-26
Abstract: PURPOSE:To increase rapid charging capability of an accumulator by a method wherein a charging plate obtained in a paste form is soaked in a nickel salt solution and a fluoroplastic membrane is formed on its surface. CONSTITUTION:Paste obtained by mixing and kneading cadmium oxide or cadmium hydroxide and a binding agent with each other is applied on a conductive core material to form a charging plate, and this charging plate is soaked in a nickel salt solution to be impregnated with nickel salt. Then a preliminary charge amount is given to the charging plate, which has been soaked in the nickel salt solution, by negatively decomposing it in an alkaline electrolyte, and then a fluoroplastic membrane is formed by soaking the charging plate in a solution of dispersed fluoroplastic. This improves the absorption capability of oxygen gas, permits the accumulator to be overcharged with a large current, and a rapid charging of the accumulator is enhanced.

Title: Semiconductor device
Inventor: OZURU ISAMU
IPC: H01L21/60
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To improve bonded states of bonding wires to bonding pads, by arranging the bonding pads in zigzag and setting lateral positional deviations of the bonding pads, so that angles between leading-out directions of bonding wires and liens connecting the centers of adjacent bonding pads may become right angles or acute angles. SOLUTION: Adjacent bonding pads 2 are arranged in zigzag against the overall arranging direction of the bonding pads 2. When bonding wires 3 led out from the lateral bonding pads 2 are alternately bonded to their corresponding lateral inner leads 4 from the top side to the bottom side, the left-right positional deviations of the bonding pads 2 are set so that the angles between the leading-out directions of the bonding wires 3 from the bonding pads 2 and the lines connecting the centers of adjacent bonding pads 2 may become right angles or acute angles. Therefore, wire bonding can be performed without forcibly reducing the diameter of the tip of a bonding tool.

Title: Electric water boiler
Inventor: KOBAYASHI HIDEAKI
IPC: A47J27/21
Filed: 1989-12-20
Abstract: PURPOSE:To mix air with steam to be jetted at the time of boiling and jet the steam after it is cooled, by arranging a steam passage with one end opened into a vessel and with the other end opened to an external side, and a cooling passage with one end opened to the steam passage and with the other end opened to the external side. CONSTITUTION:Generated steam is jetted from a steam hole 12 through a steam passage 16. On a cooling passage 37 opened near the steam hole 12 in this case, air pressure on the side of the steam passage 16 is lowered, and so air flows to the steam passage 16 from an external side. Accordingly, the air is mixed with the jetted steam, and the temperature of gas mixed at the time of jetting is made lower than the temperature of the steam. Accordingly, even if hands and a face are brought in contact with, the danger of a burn is remarkably lowered.

Title: Production of glass
Inventor: MIURA YASUTAKA
IPC: C03C6/00
Filed: 1993-12-27
Abstract: PURPOSE:To eliminate occurrence of foams caused by decomposition of a raw material and to enable stable production of glass by producing glass from synthetic sodalite as a raw material. CONSTITUTION:Glass is produced by using synthetic sodalite as a raw material. Sodalite is a mineral shown by the formula (X is CO3, Cl2, etc.) and is naturally produced in Brazil. However, in the case of sodalite of a natural mineral, part X in the formula is decomposed by heating to emit gases such as CO2 or Cl2. On the other hand, in the case of synthetic sodalite, the X part in the formula is shown by Al2O4) and no composition to become a gas-evolving source is contained. Consequently, when synthetic sodalite is used as a component source for sodium, etc., foaming in the melting process is suppressed. By the production of glass, entrapment of foams in the melting process is checked, the yield of a product is improved, a clarifying process is simplified and heat economy of a glass production process is bettered.

Ions distributed by the mask 5 of a distributing means are advanced to the work 3 by the movement of the direction applying means 6 while the distribution state is kept by the magnetic field generated by the magnetic field generating means 7. The pattern of the work is machined by the arrival or collision of distributed ions without scanning an ion beam.

IPC: H04N5/335
Filed: 1987-12-29
Abstract: PURPOSE:To evade the complication of circuit constitution for correcting image distortion by optically correcting the image ditortion occurring in the process of the conversion of sampling frequency by simple interpolation on an incident light path for a solid image pickup element. CONSTITUTION:An image pickup device 11 uses a refraction prism 12 so as to optically correct the image distortion occurring in the process of the conversion of the sampling frequency by the simple interpolation circuit 4 on the incident light path for the solid image pickup element 2. Then, as the incident light path for the solid image pickup element 2 is previously refracted and image distortion occurring as the result of the refraction is cancelled by the image distortion occurring in the process of resampling by the circuit 4, an oblique line without the image distortion can by sent to a video processing circuit 3. Thus, the complication of the circuit constitution for correcting the image distortion can be evaded.

Title: Semiconductor device and manufacture thereof
Inventor: YABU TOSHIKI
IPC: H01L21/322
Filed: 1988-12-29
Abstract: PURPOSE:To increase latch-up resistance by forming a crystal defect region into a substrate except a depletion layer region spread from each source, drain and channel region of a MOS transistor and the depletion layer region of the junction section of the substrate and a well. CONSTITUTION:Oxygen O<+> is implanted for shaping a crystal defect layer 5 into an n-well 4. Acceleration energy is selected so that the crystal defect layer 5 is formed near the peak value of the impurity concentration of the retrograde n-well 4 at that time. An element isolation 6, an nMOSFET 7 and a pMOSFET 8 are shaped, thus completing a CMOS structure semiconductor device. Since the crystal defect layer 5 has no effect on the operation of the pMOSFET 8, however, the crystal defect layer 5 is formed to a section lower than a depletion layer spread from each source, drain and channel region of the pMOSFET 8 in the n-well 4. Consequently, minority carriers causing latch-up are trapped to the crystal defect region 5, thus shortening the lifetime of minority carriers. Accordingly, latch-up resistance is increased.

Abstract: PURPOSE:To enable accurate vehicle angular speed detection even if an angular speed sensor has variance by detecting the ambient temperature, reading out the store sensitivity of the angular speed sensor corresponding to the temperature, and correcting the detected angular speed. CONSTITUTION:When the ambient temperature detected value of the angular speed sensor 11 by a temperature sensor 12 and the angular speed detected value from the angular speed sensor 11 are supplied, an angular speed arithmetic means 11 subtracts an offset value from the angular speed detected value and reads the sensitivity of the sensor corresponding to the temperature out of a temperature characteristic storage means 14 to correct the angular speed. Even if the angular speed sensor has variance with the temperature, the angular speed of wheels can accurately be calculated and detected.
